Ok look, another website that doesn't work on desktop. It's so frustrating that we seem to have lost any understanding of how to to put information on a screen.

It doesn't seem to work on mobile either, for what it's worth. Very low contrast text and general weirdness that makes it hard to tell if it's working that way on purpose or not.

Nice idea, however the readability/contrast... Author, please read: https://contrastrebellion.com/

That's one issue.

Another is how some people seem to think that you can only put one idea on the screen at a time, and users should scroll scroll scroll.

Both OP and your link both commit that sin.

Just put everything on one page and let my eyes do the moving.

How does complexity theory benefit real people? Unlike theories of physics or economics, it doesn't appear to describe how anything actually works , rather that things are just more complex than they seem. For instance, complexity theory just points out that the double pendulum is hard to predict without adding value, while controls theory was more useful by stabilizing the double pendulum. So what are some real-worl…

Complexity theory is fascinating in itself (talking about how efficiently solvable or complex a problem is in an absolute, mathematical way), but also can spur a lot of research. As an example, integer factoring is strongly believed to be hard for classical computers (in a well defined complexity theory sense). When Peter Shor presented an efficient quantum algorithm for integer factoring in 1994 it was a breakthroug…

Is complexity theory related to computational complexity? The webpage never mentioned big-O notation, and Wikipedia's disambiguation header seems to imply they're mostly unrelated: https://en.m.wikipedia.org/wiki/Complexity

You mention economics. Macro-economic theories are based on high-level relationships that economists have observed in reality, and that have some theoretical basis. For example, supply and demand can be represented as curves (aggregates of individual positions), and that in a perfect market the value of a good will converge at the intercept of supply and demand. There are a considerable number of assumptions required…

I mentioned this in another thread, but I was wondering if you had any examples of complexity theory informing what investments to make into the power grid? e.g. emergent behaviour is predictably reduced by adding X MWh of batteries in a certain region?

I recently had the (possibly flawed) epiphany that all behavior is emergent . If you think about it, all things that we consider objects are just semi-permanent aggregations of fundamental particles that we recognize and label as objects for convenience of thought. When the patterns in such aggregations are outside the space and time scales that allow human minds to recognize them, the only label available is "comple…

Philip McShane wrote something similar

"...a thing is defined by... systematizations of coincidental aggregates of the properties of lower things [and] the emergence of the systematic from the non-systematic"

I found the material from the Systems Innovation group instructive on the presence and application of some of the aspects of complexity in the real world: https://www.systemsinnovation.io/course

Thanks for the link! I'm looking for a course that really does get into the weeds about applying complexity theory to create value for my work. Would you recommend one of their listed courses in particular?

I hope to see the end of LaTex only explanations.

The site already has simulations so one must assume it has code that could codify those LaTex eqs.

Perhaps a ‘things ever ___ should know about ___’ is needed for mathematicians and notation.

Ala, “some disciplines use the same symbols for different functions” and “many symbols are intended to obfuscate details for ease of hand writing”.

Perhaps this is meant as a collection of reference material and I am wrongfully assuming complexityexplained is trying to be educational material, but if the intended audience is people hoping to have complexity explained to them then I think code and its underlying abstractions are going to better explain to a higher percentage of people who click through than LaTex.

Show both if you can.
